Whole-house repipe cost in San Diego
Quick answer
Compare pipe material, number of fixtures, routing (attic, walls or slab), whether drywall and stucco repair are included, permit and inspection, water heater connections and warranty.
San Diego's hard water and aging copper lines in many homes lead to repeat pinhole and slab leaks, which is why repipes are common. Most homes are rerouted through the attic and walls instead of the slab. Quotes vary mostly by material, fixture count and whether patching is included — so make sure you're comparing the same job.

What most people miss
Patching is often the hidden half of the price
A repipe opens many small holes in drywall and sometimes stucco. Some quotes include patching and texture; others leave it to you. Paint is often excluded. Ask exactly what the walls will look like when the plumber leaves.
How this price is built
Pipe material
PEX (and which type) or copper, with the brand named.
Fixture count
Every sink, tub, toilet, hose bib, laundry and appliance connection.
Routing
Attic and walls versus under-slab; reroutes avoid breaking the foundation.
Shut-off valves and connections
New angle stops and water heater connections.
Drywall and stucco repair
Patching, texture matching and whether paint is included.
Permit and inspection
Pulled by the plumber, with inspection before walls close.
Main line and pressure regulator
Whether the main shutoff and PRV are replaced.
Warranty
Material and workmanship terms in writing.
What makes a quote high
Patching excluded
A low price that leaves dozens of wall holes for you to fix.
Slab leak scare
Get the leak located and confirmed before agreeing to a full repipe.
Unlisted fixtures
Missing connections become add-ons once work starts.
No permit
Skipping the permit can cause trouble at resale.
Upsold water treatment
A softener may help, but it's a separate decision.
Itemised versus vague
A quote you can evaluate looks different from one you can't. This is what to look for, line by line.
| Item | A quote you can judge | A quote you can't |
|---|---|---|
| Material | PEX type or copper named | New pipes |
| Fixtures | Every connection counted | Whole house |
| Routing | Attic, wall or slab stated | Standard repipe |
| Patching | Drywall, stucco and paint terms clear | Minor patching |
| Permit | Permit and inspection included | Not mentioned |
Questions to ask before you approve
- Which pipe material and brand are you quoting?
- How many fixtures and connections are included?
- Will you route through the attic and walls or through the slab?
- Is drywall and stucco patching included? Texture? Paint?
- Are you pulling the permit and scheduling inspection?
- Are the main shutoff and pressure regulator included?
- How long will the water be off each day?
- What warranty covers materials and labour?
What to ask a San Diego repipe plumber
Copy these lines as they are. Politeness plus specifics gets answers.
- 1.“Which material, and how many fixtures are included?”
- 2.“Will you route through the attic or the slab?”
- 3.“Is patching, texture and paint included?”
- 4.“Are you pulling the permit?”
When a high price is legitimate
A higher-than-expected price isn't automatically a bad one. These are the situations where it's usually justified.
- Copper costs more than PEX in materials and labour.
- Two-storey homes and finished ceilings take more work.
- Full patching and texture matching adds real labour.
- Repeated slab leaks can make a repipe cheaper than ongoing repairs.
- Permits and inspections add fees and time.
